Lately I find myself writing data access layer select methods where the code all takes this general form:
public static DataTable GetSomeData( ... arguments)
The only thing I do differently is I switched from my own internal database helper methods to the actual Data Access Application Block http://msdn.microsoft.com/en-us/library/cc309504.aspx
Makes it a little more standardized/uniform for other developers who know the enterprise library to ramp up on the code.
